Answer:
Solve 6x – 4x – 3 = 11 for x.
Simplifying
x = 7
Step-by-step explanation:
Simplifying
6x + -4x + -3 = 11
Reorder the terms:
-3 + 6x + -4x = 11
Combine like terms: 6x + -4x = 2x
-3 + 2x = 11
Solving
-3 + 2x = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 2x = 11 + 3
Combine like terms: -3 + 3 = 0
0 + 2x = 11 + 3
2x = 11 + 3
Combine like terms: 11 + 3 = 14
2x = 14
Divide each side by '2'.
x = 7
The expressions that represent number of tiles that Devon used on her mosaic:
A. 20 + 2t + 2c
D. 20 + t + t + c + c
<h3>What is an expression?</h3>
An expression refers to a mathematical equation which shows the relationship between two or more numerical quantities or variables.
For the expressions that represent number of tiles that Devon used on her mosaic:
- Let the triangle tiles be t.
- Let the circle tiles be c.
- Two rows of t triangle tiles = t + t = 2t.
- Two rows of c circle tiles = c + c = 2t.
Mathematically, the expression is given by:
Total tiles = 20 + t + t + c + c
Total tiles = 20 + 2t + 2c.

Complete Question:
Devon made a mosaic in art class with different-shaped tiles. She started by putting 2 rows of t triangle tiles at the top of the mosaic and 2 rows of c circle tiles at the bottom. She finished by putting 20 square tiles in between the triangle and circle tiles.
Pick all the expressions that represent how many tiles Devon used on her mosaic.
A. 20 + 2t + 2c
B. 20 + 4 ( t + c )
C. 2 ( 20 + t + c )
D. 20 + t + t + c + c
Answer:
M
